How to make the life of imported bearings longer? Take the longevity digitization process of the car gearbox ball bearing as an example. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
(1) The problem of the life expectancy of imported bearings is widely used in ball bearings in passenger car gearboxes; the original service life is shorter than the extra life calculated according to the standard method juice; the performance is early fatigue and high noise. The life of bearings in other parts of the car is higher than the extra life.
(2) Analysis of the cause of the failure of the imported bearing After examination, the quality of the gearbox was outstanding; the bearing device cooperated normally; it was smooth and plentiful; it was originally suspected that the smooth oil did not enter the upper part of the bearing. However, all the inner ring channels were pressed. Traces or craters or surface cracking type fatigue; not subsurface detachment damage; do not cause such an appearance when the oil is abundant.
It was found that the outer surface of the channel was mixed with metal particles such as iron, copper, aluminum and zinc, and non-metal scraps such as rubber, sand and plastic.
Discrimination: These foreign objects and the indentations they formed damage the integrity of the oil film; the fatigue that caused the early failure of the imported bearings was verified by experiments; the above discrimination is correct.
(3) The solution to the failure of koyo bearings has been adopted to increase the steel ball type, special heat treatment type and even double row ball type and vacuum remelting steel bearings; the value is more and more valuable; and the life progress is not large.
Finally, it was developed into a "sealed hygienic" type bearing; it has achieved great success. This kind of bearing is a special rubber sealing ring on each side of the original specification bearing; the characteristic is that the sealing ring is mainly used to avoid dirt. Intrusion into the bearing; not the same as the bearing seal that is primarily intended to adhere to grease.
Second, the replacement of the smoothing agent when the koyo bearing temperature exceeds 70 ° C; the bearing temperature rises by 15 ° C; it is necessary to use the smooth grease to make up the half of the interval. The double-sided closed bearing is now loaded with grease; “HRB†is used in these products to regulate smooth grease; the common working temperature scale and other functions are suitable for the regular occasions; and the amount of grease is also corresponding to the bearing size; the service life of the grease can usually exceed the bearing life; Except for special occasions; no need to make up for smooth grease.
The smoothing oil replacement cycle of koyo bearings is different depending on the application conditions and the amount of oil; usually, it is used at an operating temperature of 50 ° C or less; in an excellent environment with little dust; once a year; when oil When the temperature reaches 100 °C; replace it once every 3 months or less.
